EMS-UL for the single use is ready to be shipped to the US.
I regret my EMS became famous as a component of the binocular telescope, before totally taking place of the traditional diagonal mirror/prism.
Of course, that’s far better than nothing, but I do regret so many senior manias still stick to the traditional diagonal mirrors with the stubborn belief of its superiority.

「裏像の方が好ましい。」というのは、どう考えても歪んだ論理、感性だと思うんですがね。
その歪んだ信仰から大方のマニアが開放されるのは、ずっとずっと先のことなのでしょうね。
まあ、それに業界が気付けば、私のような個人メーカーの出る幕はないわけですがね。＾＾；
